EC08-32

FLOW ON DEMAND PRESSURE COMPENSATING ELEMENT WITH STATIC LOAD SENSE

Overview

Description

EC08-32 is a screw-in, cartridge style, load sense, flow on demand, pressure compensator valve

Operation

With inlet flow at port 2, the EC08-32 will deliver required flow at port 3 regardless of load pressure sensed at port 1

Features

  • Range of flow ratings available.
  • Hardened parts for long life.
  • Several compensation springs available.
  • Quiet, modulated response.
  • Compact, industry-common cavity.
